Metal oxide nanosheet-type anode active material precursor, anode active material, and manufacturing method thereof for high-speed cycling stability of lithium-ion battery anodes

Method for Manufacturing Metal Oxides with High-Speed Cycling Stability via Shell Coating, Thermal Conversion, and Separation

This technology is a method for manufacturing metal oxides for lithium-ion battery anodes by coating metal hydroxide precursors with a shell, performing thermal conversion, and then separating the materials to form the metal oxide.

Conventional metal oxide anode materials suffer from structural collapse during repeated charge and discharge cycles, making it difficult to maintain cycling stability under high-speed charging conditions.

By forming metal oxides with controlled structures through shell coating, thermal conversion, and separation, this technology can be applied to lithium-ion battery anodes to improve high-speed cycling stability.

Key Features:

• A step of preparing a metal hydroxide precursor containing metal M and a step of coating it with shell-forming materials
• A step of thermally converting the shell-coated precursor in an oxidizing atmosphere to form a metal oxide
• A metal oxide manufacturing method comprising a step of separating the formed metal oxide from the shell
• A configuration where metal M is selected from nickel, cobalt, manganese, aluminum, etc., to provide high-speed cycling stability for lithium-ion battery anodes
